Application filed May 29, 1909. Serial No. 499,168.

To all whom it may concern:

Be it known that I, EBEN G. DoLA vn, a

citizen of the United States, and a resident of Starksboro, in the county of Addison and State of Vermont, have invented a new and Improved \Vagon-Brake, of which the following is a full, clear, and exact description.

This invention relates to an automatic brake, which is adapted tobe used in connection with carriages, wagons or the like, and is so arranged that it may be either thrown on by hand or applied by the backing of thehorses connected to the tongue of the wagon.

An object of the invention is to provide a .device which will be simple in construction,

easily and quickly operated, and at the same time strong and durable.

A further and important object of the invention is to provide .means whereby the brakes may be applied by backing the horses,

' and in such a manner that there will be no strain upon the mechanism in traveling around curves or over rough roads.

Astlll further ob ect is to provide means for locking the'brake-ope'rating mechanism out of operation.

- -These and further objects, together with the construction and combination of parts,

willbe more fully described hereinafter and Y particularly set forth in theclaims.

' Reference'is to be had to the accompanying drawings fonnin a part of this specifi cation, in which simi ar' characters of reference indicate corresponding-parts in all the.

views, and in which- I Figure 1 isa vertical longitudinal section through a wagon having my braking mechanism attached thereto; Fig. 2 is a bottom plan view; Fig. 3 is a vertical transverse section on theline 3'-3 of Fig. .1; Fig.4.- is

a vertical detail transverse section on the line'44 of Fig. 2, showing the guiding rollers for the brake-reach; and Fig-dis a longitudinal detail section ing mechanism.

Referring more particularly to the parts ofthe device, 6 indicates the-body of a through the lockwagon, which is supported on trucks 7 and 8, which in turn are connected in any wellknown manner by a reach-bar 9. The trucks 7 and 8 are suitably supported by wheels 9 and 10, which are rotatably connected to shafts 11 and 12 'on the trucks 7 and S.

The front truck 7 is pivoted to the reachba 9 in any well-known manner, as by means of a king-pin, and'ha-s at the forward end thereof a suitable tongue-support 13, which 15 pivoted to the truck on a horizontal rod L or bolt 14, which allows an np-and-down motion. of the tongue-support relative to the truck and the wagon.

Shdmgly secured in the tongue-support 13, there is provided a suitable tongue 15,

to which horses or the like may be attached,

to draw the vehicle. This tongue 15 slides in the tongue-support 13 between suitable retaining members 16 and 17, which are secured in any well-known manner to the tongue-support 13. The sliding motionof :the tongue 15 ispermitted by reason of the Facing the roller 20 and adapted to co-act therewith, there is provided a similar roller 21, which, however, s pivotally secured to a brake-reach 22, at right-angles to the roller '20. Themethod'of securing the roller 21 to the vbrake-reach 22 consists in having a air of metal brackets 23, which are secure any well-known manner to the brake-reach 22 and extend along the sides of the wagonreach 9, and have suitable pivots at their outer ends, to which theroller 21 is rotatably secured.

In order. that there may not be an excessive frictionof the brackets 23 on the sides of the wagon-reach 9, there are provided suitable anti-friction rollers 24 and 25,

which are rotatably supported in a suitable bracket 26 secured to the wa on-reach 9.

The brake-'reach- 22 is parts, ,which are adjustable relative to each other by any suitable means, such as a lurality-of bolts 27, passing through allned perforations in the over-lapping ends. To

the rear-end of the brake-reach 22, there is pivotally secured in any well-known manner a bifurcated l'ever28, which extends to either side of the wagon-reach 9, andis fulcrunied on a suitable supporting bracket 29, which is secured in any well-known manner to the rear truck 8.; [Intermediate the connecting point of the lever 28 tothe brake-- reach 22 and its .fulcrum29, there is proormed in two end to a U-sha ed bracket35 wheels 10.

levers to the front vided a suitable securing means-to which a connecting chain 30 is attached, said connecting chain being secured at its opposite end to a brake-beam 5-31, which. has brakeshoes 32 on each end thereof, which are adapted to engage the wheels 10. The brake beam 31 is flexibly supported in any well kuown manner to the running gear of the-wagon, as by means of links 33.

In order to hold the brake-shoes and beams away front the wheels provided a suitable spring 34, which is connected at one end in any well-known manner to the brake-beam 31, and at the other which is secured in any well-known manner to the un der side of the wagon-reach 9.

As far as has been described, it will thus be seen that the backing motion'of the horses connected to the tongue 15 will force the brake-reach 22 backward, and thus draw the brake-shoes 32 into engagement with the when the horses start up again, the spring 34 will automatically withdraw the brake-shoes from the wheel. The brake may also be thrown in by hand, by means of a lever 36, which is secured to a cross shaft 37, which is pivoted in any well-knowir manner to the under side of the rear truck, and has one or more lever-arms 38 secured thereto which are adapted to draw the brake-beam 31 toward the wheels 10 by means of suitable flexible Connections, such as chains 39. This lever 36 may be connected up by suitable connecting links and end of the wagon, if desired. i

In order to back the wagon without throwing in the brakes, there is=provided a suitable locking mechanism on the tonguesupport, which prevents the relative motion of the tongue and tongue-support. For this purpose, there is provided a. suitable lock 40, which is pivotally secured in brackline position shown in" Fig. 5.

ets 41 secured in any well-known manner to the tonguesupport 13. This lock 40 has an engaging flange 42, which is normally spring-pressed away from a flange 48, secured in any well-known manner to the tongue 15. In order to lock the flange 42 in engagement with the flange 43, and thus prevent rearward motion of the tongue, there is provided on the opposite end of the lock 40, a pivoted latch 44, which is adapted to ejigage a ridge on a suitable spring member 45, and thereby hold the flange-end 42 of the lock member 40 down in the dotted- In order that the lock 40 may be manipulated by a driver on the vehicle, there is provided a suitable flexible connection 46, which is attached to the lock 40 at one end, and has a link 47, which is adapted to engage a suitable hook 48 on the vehicle, by means 0 which it is fastened to the vehicle. There 10, there is l is also provided on this 46 an intermediate link the manipulation of the lock adapted to support the lock position.

In certaintypes of wagons, and for. ccrtain purposes in the same wagon, it is desirable to have the brakereach below the wagon-reach. I have therefore provided on the transverse shaft 37 a pair of arms 50, to which the brake-reach may be pivoted and thus operate the brake-beam through the same means utilized by the lever. 36 to throw the brakes into engagement with-the wheels 10. In this case, the brake-reach 22. would be supported by the Ushap'ed bracket 35.

From the above description, it will readily be seen, that a strong and efficient device has been provided, by means of which the brakes may be set on the wagon, either by hand or by the backward pull of the horses on the tongue. There has also been provided means whereby the automatic tongue-braking mechanism maybe locked out of operation, so that the driver may back the vehicle, i he so desires, without setting the brakes. By reversing the flange 43 and its pivotal connection with the tongue, the latch 40 may be made to engage this flange so as to lock the brakes in their set position. It will also be seen that the engaging beveled rollers 20 and 21 provide a simple and ethcient means for permitting vertical and horizontal motions of the tongue relative to the wagon, without causing a strain to be placed on the braking mechanism, and yet which will provide a positive and quick-acting connection between the tongue and the brake.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1* 1.
